Before you doodle mystic symbols in your notebook or get meta-spiritual tattoos inked on your body, consider what types of spirits those strange sigils may invoke. Some symbols might seem familiar, and even safe enough to appear on everyday items like Oreo cookies. However, they shouldn't necessarily be displayed by ordinary folks unless you're trying to get yourself into some seriously dark stuff.
Just like how some forbidden words act as incantations (and invitations) for sinister energy, some satanic symbols are too dastardly or ominous to be advertised by just anyone. These symbols are powerful runes that can invite dark spirits into your vicinity. Whenever you see these symbols, keep your head on a swivel. Otherwise, you're just asking to hang out with whatever diabolical being has been summoned as a result of someone else playing fast and loose with symbols intrinsically connected to mystic forces.
